<P>PROBLEM TO BE SOLVED: To provide an ultraviolet absorber which does not cause deposition of the ultraviolet absorber and bleed-out caused by long-term use, is excellent in the long-wavelength ultraviolet absorption performance and the light fastness while maintaining the absorption performance for a long period of time. Ž<P>SOLUTION: The ultraviolet absorber is represented by general formula (1), wherein, A represents an ultraviolet absorbing residue; B represents a photostable residue; L represents a linking group containing at least one nitrogen atom; and x, y and z each independently represents an integer of ≥1.
